Yes, because the setup.ini file does not list 2.4 as either 'prev',
'curr', or 'exp'.  Those are the only three versions you can select in
setup.exe when installing from the internet.

Correct.  You can, theoretically, just run the postinstall scripts
manually, but there is a better way.

No command-line tools[*], but you can do the following:

1) Download the package to some subdirectory of your Cygwin package cache
directory, e.g., C:\install\Cygwin\custom.
2) Setup should be smart enough to infer the version, but, just to make
sure, you can create a custom setup.ini with that one package in it,
setting 'curr' to the version you want (i.e., 2.4).  See
<http://www.cygwin.com/ml/cygwin/2007-07/msg00134.html> for an example of
such a setup.ini (except you'd need one with a "python" package).
3) Tell setup to "Install from local directory".  That should let you
select 2.4, and setup will install it.

[*] You can also run setup in unattended mode (as described in the above
link), but it may require more elaborate manipulation of setup.ini.
HTH,
